Research and development activities concerning fodder trees involve a wide range of scientific disciplines including, among others, agroforestry, ruminant nutrition, biochemistry and farming systems research. This paper aims to explore some of the genetic resource issues relevant to the development of tree fodder for tropical farmers, and to emphasise the importance of giving consideration to these issues even in areas of research not primarily concerned with genetic variation. Evaluation methodologies will be illustrated using the examples of Gliricidia sepium and species of Leucaena, widely distributed and highly researched leguminous fodder trees which have been the subject of worldwide genetic improvement research networks. Issues relating to conservation and genetic improvement of tree fodder resources at a more local level will also be discussed.
